Abstract: 1275287 Boots &c BATA SHOE CO OF CANADA Ltd 3 June 1969 [3 June 1968] 27923/69 Heading A3B In a machine for automatically roughing the overlasted margin of a shoe of the type in which the shoe is moved past a pair of rotary roughing tools 2, the longitudinal and transverse angular relationship of the tools 2 are automatically varied at selected points in the roughing cycle and the pressure exerted by the tools 2 is automatically varied during the roughing cycle. Each tool 2 is mounted in a frame 22 for rotation about a transverse axis under the control of pneumatic cylinder 21 and the frame 22 in turn is mounted for rotation about a longitudinal axis under the control of pneumatic cylinder 30. Cams (not shown) on the last carrier control the cylinders 21 and 30 so that each tool assumes its correct longitudinal (Fig. 4) and transverse positions with respect to the shoe bottom. The tool carriers are mounted on slides 14 which can slide on vertical rods 4 and which are connected via a rocker to counter balance cylinders 46. The cylinders 46 can be connected to air at high, medium or low pressures so that the tools can exert low pressures in the toe region 38, high pressure in the shank region 40 and medium pressure in the heel region 42. The pressure is again controlled by cams (not shown) on the last carrier. The heel of the last 62 (Fig. 9A) is correctly positioned heightwise by mounting the last 62 on a spring loaded last pin 94 and depressing the heel by piston rod 122 until the last is in its correct position. The last is held in this position by a ratchet 106 and pawl 108 which is released by a cam 112 at the end of the roughing cycle.

Title: Improvements in or relating to the measurement of fluid flow
Inventor: DUFFY LAWRENCE SIDNEY
IPC: G01F1/075
Filed: 1967-06-16
Abstract: 1,183,503. Measuring fluid-flow electrically. GEORGE KENT Ltd. June 11, 1968 [June 16, 1967], No.27979/67. Heading G1N . Rotation of a turbine flowmeter, provided with a magnetized disc on its shaft or with magnetized inserts in the turbine blades, is sensed by a semi-conductor detector, e.g. a Hall plate or a magneto-resistive element. As shown, the turbine may be axially aligned with the fluid-flow direction, Fig. 2 and Figs. 1, 3, 4 (not shown), or with its axis on right angles to the flow, Fig.6 and Figs.5, 7, 8 (not shown), and is provided either with a diametically magnetized disc 18, Fig. 2, on the turbine shaft or with magnetized inserts 68 in the blades Fig. 6. One or more Hall plates 24 or magneto-resistive elements are equally spaced round the disc or turbine blades. The Hall plate 24 may be D.C. energized, Fig. 9 (not shown), and its output rectified or it may be A.C. energized, Fig. 10 (not shown), and its output demodulated. Alternatively it may be connected in the feedback circuit of an amplifier, Fig. 11 (not shown), provided with a C.R. circuit, so that the amplifier produces an A.C. output, whose frequency is determined by that of the C.R. circuit, only when the Hall plate emits a positive pulse. In all the above examples the final pulsed output is shaped to provide squarewave pulses which are fed to a counter to provide an indication of flow-rate. If a single magneto-resistive element is employed, it may be connected together with a fixed resistor across an D.C. or A. C. supply, Figs.12, 13 (not shown), the output being rectified or demodulated and shaped as required. For temperature compensation the fixed resistor may be replaced by a second magneto-resistive element, Fig.16 (not shown), which is screened from the magnetic field. If a plurality of magnetoresistive elements are used, Fig.17 (not shown), they may be connected in parallel in series with the fixed resistors. Alternatively, for two magneto-resistive elements positioned 180 degrees or 90 degrees apart, they may be connected in opposite arms of a Wheatstone bridge, Figs.14, 15 (not shown). As before, in each case the pulsed output is shaped to form a squarewave pulse.

Filed: 1961-08-03
Abstract: A compound of structural formula: <FORM:0964718/C1/1> where Y is chlorine, is prepared by chlorinating trithiocyanuric acid.  In a example a slurry of trithiocyanuric acid in carbon tetrachloride was added to a solution of chlorine in carbon tetrachloride at - 10 DEG C.  The mixture was then allowed to stand at room temperature for 16 hours.  It was then filtered and evaporated under vacuum and the triazine trisulphenyl trichloride filtered off.  The compound may be used in curing polymers (see Division C3).ALSO:The invention comprises thiocyanuric acid derivatives having the general formula: <FORM:0964718/C1/1> where Y is-RCl wherein R is a divalent aliphatic hydrocarbon radical having its two free valencies on vicinal carbon atoms. These compounds may be prepared by reacting the 1,3,5 triazine 2,4,6 trisulphenyl trichloride with an aliphatic olefine. In one example the triazine trisulphenyl trichloride is reacted with 1 mol. of isobutene in toluene in a pressure bottle at ambient temperatures. In another example 1-octene is used similarly. The compounds formed may be used as curing agents for rubbers (see Division C3).ALSO:Polybutadiene, polyisoprene and isobutyleneisoprene copolymers may be cured by incorporating into the polymer a compound of the general formula: <FORM:0964718/C3/1> where Y is Cl or -RCl, wherein R is a divalent aliphatic hydrocarbon radical having its two free valencies on vicinal carbon atoms.  The compound is incorporated into the polymer on a mill and maintained at an elevated temperature. Examples describe the curing of various of the above polymers using the trithiocyanuric acid chloride or the chloro-isobutyl di-chloro or chloro-octyl di chloro derivative, carbon black sometimes being incorporated in the mixture.

Title: Centrifuges
Inventor: HARBOTT NORMAN RICHARD
IPC: B04B5/00
Filed: 1967-06-19
Abstract: 1,189,195. Centrifuges. MSE. HOLDINGS Ltd. 27 July, 1967 [17 June, 1967], No. 28277/ 67. Heading B2P. In a zonal centrifuge having a casing 1 within which a cylindrical rotor 8 is driven at its lower end by an electric motor, the rotor extends through an aperture 9 in a cover 2 of the casing and is rotatably supported at its upper end in a bearing within a housing 10 which carries an arrangement 11 for liquid supply and exit to and from the rotor respectively. The housing 10 comprises an annular portion 12 which fits within the aperture 9, an O-ring 13 providing a vacuumtight seal between the cover 2 and the portion 12. The cover 2 is sealingly slidable on the casing 1 which is under vacuum. The rotor is surrounded by a bowl 6 secured to the housing of the driving motor and surrounded by cooling coils. Coolant is fed at 20 and 21 to a top bearing 22 and a rotating seal 23 respectively. In operation, coolant is fed to bearing 22 and seal 23 and the rotor is first run at slow speed so that an O-ring valve 26 seals off the passage 25. A gradient solution is pumped into the rotor, light end first, through tube 18 and passages 24 until the rotor is full as indicated when the light end of the solution flows through passages 30, 28 and emerges from tube 19. The rotor is then run at high speed, when the valve 26 opens. A particulate sample, e.g. virus, in a carrier liquid of density lighter than the inner, lightest zone of the gradient solution in the rotor, is introduced continuously through the tube 19. The carrier liquid enters the annular rotor space 17 at its lower end, travels along the outer surface of the rotor core 29, enters the passages 27 and eventually emerges from the tube 18. The sample particles leave the carrier liquid during its passage through the rotor and become distributed into zones of the gradient solution according to their densities. The rotor may then be unloaded by reducing its speed to close valve 26 and by pumping a fluid of density greater than the densest part of the gradient solution through tube 18. This displaces the gradient solution, lightest end first, through the tubing taking with it the separated bands of the sample particles. The description refers to a known centrifuge made of TITANIUM.
